gcc 4.9.2 is ok

[Glee1018]

Hi, I'am very glad to get your email. Yes, it is a GCC version issue,  and my code works well with gcc 4.9.2, 5.2 and 6.3, maybe you can try 4.9.2 or above. I hope you will soon solve this issue.

Hi,

I am facing this same issue. Would you be kind enough to help me figure out the issue? Is it a GCC version issue? My current gcc version is 4.8.5.

Hi,

I was able to resolve it by rebuilding with a higher GCC version, and hence had deleted my comment. Thank you very much for your response!
